Unit 5: Arson and Explosives
Across
- 10. _________ liquids are almost never directly consumed during a fire.
- 12. temperature that fuel must reach in order to allow the heat energy input to exceed the energy barrier.
- 13. natural gas, propane (LP), oil, coal, wood, electricity, heat pumps, ground source heat pumps and solar energy.
- 14. the most burnt area of a fire
- 15. the lowest temperature in which a liquid will form a vapor in the air next to its surface
- 18. any substance or mixture that accelerates or speeds the development and escalation of fire.
- 19. reacts at a speed slower than the speed of sound in the substance
- 20. the extremely rapid burning of a material
Down
- 1. the decomposition of organic matter by heat
- 2. A __ ____ could indicate a pool of an accelerant.
- 3. the sudden and violent release of mechanical, chemical or nuclear energy from a confined space which creates a shock wave that travels at supersonic speeds.
- 4. dynamite, C4 and TNT and are used in commercial and military blasting.
- 5. Arson investigation is difficult because fire destroys most evidence and the rest is often washed away by _.
- 6. a unit of measurement that shows just how much energy your air conditioner uses to remove heat from your home within an hour.
- 7. Once the point of origin has been located, any ash, soot, and porous materials is collected and stored in ________ containers.
- 8. a pattern that indicates that a fire burned "normally" and therefore does not suggest the use of an accelerant.
- 9. indicates that a fire burned hotter than normal because it spread vertically more quickly than horizontally.
- 11. accompanied by, or requiring the absorption of heat
- 16. a reaction that releases energy
- 17. paper, oils, wood, gases, fabrics, liquids, plastics and rubber.
